Stationary Music from Users' Viewpoint in VR Applications

摘要

The ultimate goal in virtual reality (VR) is to achieve complete immersion in terms of audio and video, where background music is typically included to keep users absorbed in a game or 360-video content. This paper explores a multichannel loudspeaker configuration to anchor the background music to the user's viewpoint in VR. To that end, an evenly-spaced octagonal loudspeaker configuration is implemented in order to anchor the background music using head tracking data. The real-time panning is achieved through Vector-Base Amplitude Panning (VBAP). This paper also describes a demo interface built using the Oculus Rift in Unity and Max/MSP, as proof of concept.
